ALA VlP-STOVE.

SPEIFICATION forming part of Letters Patent No. 309,713, dated December 23, 1884.

Application tiled February 5,1884.

To @ZZ whom, 25 may concern.-

Be it known that I, CHARLES T. HAM, of the city of Rochester, in the county of Mon roe and State of New York, have invented new and useful Improvements in Lamp-Stoves, of which the following is a specification.

This invention relates to an improvement in Y that class of stoves which 'are provided with wick-burners adapted to burn kerosene and similar oils, and has for its object to render the air-supply to the burner more steady and uniform than heretofore, to facilitate the exit of the products of combustion, and to improve the means whereby the rear end of the n1ovable top portion of the stove is supported upon the base of the same.

My invention consists, to these ends, of the improvements in the construction of thestove, which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of three sheets, Figure I represents a longitudinal `vertical section of niyimproved stove. Fig. 2 is a longitudinal cross-section through the front portionof the stove. Fig. 3 is a rear elevation of the device, whereby the rear end of the top portion is supported upon the base. Fig. 4 is a horizontal section in line a: x, Fig. l. Fig. 5 is a top plan view of the outlet for the products of combustion. Fig. 6 is a vertical longitudinal section, on an enlarged scale, of the lower portion ofthe stove. Fig. 7 is a sectional elevation of a modified form of my improved stove.

Like letters of referen ce refer to like parts in the several iigures.

A represents the base of the stove, A the oil-reservoir secured in the same, and ct the wicktubes .projecting upwardly from the oilreservoir. K

B represents a closed air-chamber arranged above the oil-reservoir, and inclosing the upper ends ofthe wick-tubes c.

c represents the elongated burner-cones, which surmount the upper ends ot' the wicktubes a, and which are cast in one piece with plates C. The latter are seated iu openingsin the top plate, I), of the air-chamber B.

D represents the flame-chambers arranged above the burner-cones, and E the topI chamber, which connects the two flame-chambers D, and 'which has its top plate, e, provided (No model.)

with openings e' e2, for the reception of the cooking utensils. A single flame-chamber, D, may be employed, if desired. The airchamber B is closed on all sides, its only outlets being forrned by the slots of the burnercones c.

F represents elevated perforated air-chambers communicating at their lower ends with the air-ehamber B by openingsf, formed in the top plate of thelatter. The airchambers F are preferably cylindrical in form, as shown, and secured to the air-chamber B by vertical bolts g, passing through the tight top plates,

f, of the air-chambers, and through the bottom plate, b', of the air-chamber B. Thelower end of the cylindrical wall surrounds'a collar formed on the upper side of the air-chamber B, around the opening f in the same.

The cylindrical walls of the air-chambers F are constructed of finely perforated sheet metal, which permits the air to enter in ne jets or streams only, thereby preventing the disturbingeffects on the flame, which would be caused by the sudden entrance of a large volume of air into the air-chamber B. The burners draw their supply of air from the airchamber B by reason of the chimney action of the flame-chambers D. The air is supplied to the burners from the air-chamber B in a stead y and uniform manner, thereby maint-ainiug a steady and smokeless flame, and the airchamber B in turn is supplied with air from the air-chambers F. The air-jets entering througlrthe perforations of the chambers D are reduced gradually to a state of comparative quietude by passing first throughl the chambers D and then through the closed chamber B. The'elevated air-chambers D offer a large aggregate area to the entrance of the air. and cause a copious How of air to the air-chamber B, from which the flames are fed. I

lVhen the stove is designed for outdoor use, or for use in localities where it is exposed to strong air-currents, the air-chambers F are preferably provided with internal perforated cones, H, which depend from the top plates of the air-chambers and direct the air entering through the perforations of the outer wall toward the openings f in the air-chamber B.

I represents a removable cover applied to the rear opening, et, and adapted to support a cooking utensil, and at the same time permit ICO of the escape of the products of combustion. The cover I is provided in its bottom plate with openings t', through which the products of combustion escape from the top chamber,E.

ffl is a flange formed on the under side of the bottom .plate of the cover I, to tit in the opening c2. The cover I is provided with an upwardly-Haring marginal flange, i2, which prevents the wind from blowing into or across the openings z', which would react on the flame and cause smoke.

i are supporting-studs formed on the bottom plate ofthe cover I, and made lower than the flange ft2, so that the bottom of the cocking utensil is below the top edge ofthetlange il" represents ribs formed on the inner side of the flange i?, to form a free space around the cooking utensil for the products ot combustion. rlhis cover can be removed when -the oven is placed on the rear opening, iP.

rlhe plates C are firmly secured to the lower ends ofthe llame-chambers D, and rest,a loosely upon the top plate, b, ofthe air-chamber B, being contined on the same by llangcsj, formed on the top plate, b.

k represents lugs formed on the upper side of the top plate, b, in front of the rear edge of the plate C, so as to limit the forward movement ol' the downwardly-curved edges of the plate C on the top plate, b, of the air-chamber B. Upon turning the top portion of the stove backwardly to expose the wick tubes, the rear edges of the plates C are held between the flange j and lugs 7.1, and form a fulcruln on which the top portion of the stove swings.

L and M are two upright bars, whereby the rear end of the top portion ofthe 'stove is supported upon the base A. The bar L is secured to the under side of the rear end ot the top portion, and rests with its lower end upon the upper end of the bar M, which latter is adjustably secured to the rear portion ot' the base A. The upper end of the lower bar, M, is provided with a socket, m, having an inclined bottom, whereby the lower end ot' the upper bar, L, is held firmly in place. The lower bar, M, is attached to the base A by a slotted foot, N, and screwa, in such ina-nner that it can be moved backwardly and forwardly on the base. Upon moving the bar M backwardly to the position represented in Fig. l, the bar M supports the bar L and the top of the stove in its normal position. Upon moving the bar M forwardly the bar L drops down until it rests on the base A, as indicated in dotted lines in Fig. I, and the top portion cl' the stove turns on the rear edge ot' the plate C, which is confined between the ilangej and lug 7:, thereby exposing the upper ends of the wick-tubes.

I do not intend to claim anything inthis application which is claimed in my pending application, No. 114,053, filed December 10, 1883.

I am aware that perforated plates and perforated tubes have been used in various ways for supplying air to a llame, and I do not broadly claim such parts; but

I claim as my inventionl. rIhe combination, in a lamp-stove, of a wick-burner and burner-cone, a closed airchamber arranged below the burner and communicating with the under side of the burnercone and supplying air thereto, and an elevated perforated ai r-chamber adapted to contain a body of air, and which surmounts the air-inlet opening of the closed air-chamber, and permits the entrance of air only through its perforations, substantially as set forth.

2. The combination, in a lamp-stove, of a wick-burner and burner-cone, a closed airchamber communicating with the under side of the burner-cone and supplying air thereto, a perforated air-chamber which surmounts the air-inlet opening of the closed air-chamber and permits the entrance otl air only through its perforations, and a delleetor arranged within said perforated airchamber, and adapted to direct the air toward the air-inlet opening of the closed air-chamber, substantially as set forth.

3. rIhe combination, with a wicleburner, a, and burner-cone c, ot' the closed air-chamber B, having an air-inlet opening, f, a perforated chamber, F, provided with a top plate, f, and a bolt, g, whereby the chamber F is secured to the chamber B, substantially as set forth.

4t. rlhe combination, with the dame-chamber D, having a flanged bottom plate, C, of the air-chamber B, provided on its upper side with a flange, j, and lug k, between which the rear edge of the lianged bottom plate, C, is conlined, substantially as set forth.

5. The combination, with the base and the movable top portion of a lamp-stove, of supporting-bars secured, respectively, to the base and top portion, and made adjustable with reference to each other, whereby the rear end of the top portion of the stove is supported in its normal position when the supportingbars are engaged with eac-h other, and permitted to drop when said bars are disconnected, substantially as set forth.

(i. rIhe combination, with the base and the movable top portion ot' a lamp-stove7 ot' a supporting-bar, L, secured to the top portion, and a supportingbar, M, attached adjustably to the base, substantially as set forth.
